BRAIDING-MACHIN E.

To all whom it may concern:

Be it known that I, Amman PETERSEN, a citizen of the United States, andresident of Boston, in the county of Suffolk and State of Massachusetts,have invented new and useful Improvements in Braiding-Machines, of whichthe following is a specification.

This invention relates to rotary braiding machines, and particularly tobraiding machines of the type having a main revolving frame Within whicha series of thread carriers are revolved in the opposite direction by arevolving roller frame, the main revolving frame carrying strand guidesfor passing the strands over and under said thread carriers. Theinvention consists in the novel'features of construction hereinafterdescribed and particularly pointed out in the claims. I

In the accompanying drawings which illustrate one embodiment of theinvention, and show such parts only of the braiding machine as a wholeas are necessary for an understanding of the novel features of theinvention,

Figure 1 is a vertical section of a part of a braiding machinecontaining the invention;

Fig. 2 is a fragmentary view, partly in plan and partly in horizontalsection, of a pair of rollers and friction wheels carried by therevolving roller frame; and V Fig. 3 is an end view of one of saidrollers and the friction wheel secured thereto.

Referring to the drawings, 1 represents the frame of the machine,preferably made spider sha ed, and provided with a central hub 2 whicsupports a central tubular shaft 3, at the top of which the fabric isformed.

The shaft 3 is' sur'rounded by a sleeve 4 which is rotatable on shaft 3and has secured to it, by nieans of a set screw 6, a bevel gear 5 whichrotates on the upperface of hub 2. Thebraide'd fabric passes downthrough the hollow shaft 3 to a takeup mechanism of usual construction(not shown). A driving shaft -7journaled in bracket 8, carried by themain frame, is provided at its inner en'd with a'pinion 10 Specificationof Letters Patent.

which meshes with and drives the bevel gear 5.

Upon the sleeve 4. above the bevel gear 5 is a revolving frame 11 whichsupports the strand guides (not shown) in the usual way,

and is revoluble 0n sleeve 4. The frame 11, which may be termed the mainrevolving frame, is provided with a bevel gear 12 on its under sideengaging the pinion 10. Thus the frame 11. and the parts carried therebyare caused to revolve in opposite directions to the sleeve a and theparts carried thereby.

Above the frame 11 is a disk 13 fast on sleeve 4- and turning therewith,to which are secured concentric annular rims 14 and 15 connected byradial arms 16, the inner rim 14 being mounted on the disk 13. The disk13 with its rim and radialarms may be termed the roller frame. In eachof the segmental spaces between the rims 14 and 15 and the arms 16,there is journaled a pairof rollers for supporting and driving thethread carriers hereinafter described, each roller comprising an outerroller element 17 and an inner roller element 18 connected by a shaft 19disposed radially of the roller frame and journaled at its ends in therims 14 and 15.

A friction wheel 20 made of felt or other suitable compressibleresilient material, is fixed to the outer side of each roller 17 so thatit rotates therewith. Preferably said friction wheel is in the form ofan annulus secured to the outer face of the roller 17 by means of aWasher or rin 21 secured to the roller 17 by screws 22. r aid annularfriction Wheel 20 and said washer wheel 21, as herein shown, are fittedover the outside of a flange or rim 17 on the roller 17. Thus thefriction wheels are readily removable and replaceable in case theybecome worn or damaged. A ledge or flange'23 is secured to the innerside of the upright portion 24 of the main revolving frame 11, and thefriction wheels 20 run on said ledge 23 thereby rotating'the supportingand driving rollers 17-18.

A series of thread carriers 25, each adapted" to carry a cop or massof'thread, are

mounted in the several segmental spares between the rims l4 and 15 andarms it), earh being supported and driven by one of the pairs of rollerson the roller fram At lhe inner end of each thread rarrirr L in; aroller 26 resting on a pair ol rollers lb, and at the outer end of eachthread carrier is a roller QT r sling on the corresponding pair ol'outer rollers 17. Said thread rarriers may also have horimniallydisposed rollers 28 which run in guideivzrvs 21.] on the main revolvingl'ranie to talv up the entrifugal thrust as the said carriers revolveabout the machine. l larh thread arrier may also have a roller 30 at thetop, aiding in resisting centrifugal thrust, and cooperating with guardring 31 to prevent the thread carrier from being dislodged inwardly fromits position.

As the main revolving frame and the roller frame are revolved inopposite dired tions about the machine. and the tl'iread or strand '1 isarried over and under the thread carrier in the usual manner, the passage of the thread "l between the lhrcad arrier rollers and thesupporting and driving rollers is aided by the rotation of the saidrollers by means of the friction wheels travcling on the ledge 23 on themain revolving frame. The relatively positive drive of said rollerscaused by said friction wheel is of especial advantage Where the machineis operated upon light material which would be likely to break if therollers were idler rollers and the tension of the thread itself wererelied upon to pull the thread between the rollers.

I claim:
